Celery cannot connect to RabbitMQ server

Question

I am trying to run celery and it is unable to connect to the RabbitMQ server even though I have correctly set the user, vhost and assigned the appropriate tags

celery -A proj worker -l info

The above command returns the error

[2021-09-28 18:05:37,649: ERROR/MainProcess] consumer: Cannot connect to amqp://test:**@12:5672//: timed out.
Trying again in 2.00 seconds... (1/100)

I have initialized the celery app as follows

app = Celery('proj',
             broker=f'amqp://test:test@12#4@localhost/test_vhost')

---

I believe this is not working because the password test@12#4 has the special characters @ and # in it.

How do I get this to work without changing the password.

Answer 1

Sorry there is no way to use such passwords with '@' characters , this is already a known issue with the Celery and the reason is due to urllib3 parse functionality . The only way around is to remove such characters from the password.

For reference please look up the corresponding github issue here

Answer 2

This issue can be solved using escape sequences.

The issue is not with the @ character but with the #

So if your password is test@12#4 , you can simply use the escape sequence for the # character which is %23

The password can be written as test@12%234
